RECENT SCATTEROMETER DATA SHOW LIGHT TO GENTLE NW WINDS ACROSS
THE OFFSHORE WATERS OFF BAJA CALIFORNIA WHILE ALTIMETER DATA
INDICATE MODERATE SEAS TO 6 FT, WHICH IS BEING INFLUENCED BY
MIXED SW AND NW SWELL. IN THE GULF OF CALIFORNIA, WINDS ARE
FRESH FROM THE SE WITH 3 TO 4 FT SEAS. STRONG N WINDS PREVAIL
ACROSS THE GULF OF TEHUANTEPEC, WHERE SEAS ARE ESTIMATED TO BE
7-8 FT. ELSEWHERE, WINDS ARE MODERATE OR WEAKER AND SEAS ARE
MODERATE IN SW SWELL.
FOR THE FORECAST, MODERATE OR WEAKER NW WINDS WILL PREVAIL ACROSS
THE BAJA CALIFORNIA OFFSHORES THROUGH TUE NIGHT ALONG WITH SLIGHT
TO MODERATE SEAS IN MIXED SWELL. FRESH TO STRONG SE WINDS ACROSS
THE GULF OF CALIFORNIA WILL DIMINISH TO GENTLE TO MODERATE SPEEDS
BY LATE SAT. PULSES OF FRESH TO STRONG NORTHERLY GAP WINDS ACROSS
THE GULF OF TEHUANTEPEC WILL REACH NEAR GALE-FORCE SPEED MON
NIGHT, WHICH WILL CONTINUE TO AFFECT THE REGION THROUGH AT LEAST
MIDWEEK. OTHERWISE, AN AREA OF LOW PRESSURE IS EXPECTED TO FORM
LATE THIS WEEKEND OR EARLY NEXT WEEK SEVERAL HUNDRED MILES SOUTH-
SOUTHWEST OF THE COAST OF SOUTHWESTERN MEXICO. ENVIRONMENTAL
CONDITIONS APPEAR FAVORABLE FOR GRADUAL DEVELOPMENT THEREAFTER,
AND A TROPICAL DEPRESSION IS LIKELY TO FORM NEXT WEEK WHILE THE
SYSTEM MOVES GENERALLY WEST-NORTHWESTWARD. REGARDLESS OF TROPICAL
CYCLONE FORMATION, THE LOWERING PRESSURE MAY INDUCE AT LEAST
FRESH TO STRONG WINDS AND ROUGH TO VERY ROUGH SEAS ACROSS THE
OFFSHORE WATERS OF SW MEXICO SUN NIGHT THROUGH TUE NIGHT.
